AGlTATOFi FOR M IXED PAINTS.

SPECIFICATION forming part of Letters Patent NO. 500,073, dated June 20,1893.

Application filed fieptember 29, 1892. Serial No. 447.238. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES JOHN MOLEN- NAN, master painter, residing inthe city of Toronto, in the county of York, in the Province of Ontario,Canada, have invented certain new and useful-Improvements in Agitatorsfor Mixed Paints, of which the following is the specification.

The objectof the invention is to design a means whereby paint when mixedmaybe prevented from settling and itconsists essentially of a frameprovided with downwardly extending tongues or beaters which frame issupported in guides so that the downwardly projecting tongues areslightly above the bottom of the receptacle, which contains the paint,and derives a reciprocating vibratory motion from a vertical spindledriven by any suitable motor as hereinafter more particularly explained.

Figure 1, is a perspective view of areceptacle for paint showing aportion of the side broken avs ay so as to exhibit in perspective thegeneral construction of my agitator frame. Fig. 2, is a cross sectionthrough Fig. 1. Fig. 3, is an enlarged detail showing my approved methodof constructing the tongues or beaters.

In the drawings like letters of reference indicate corresponding partsin each figure.

- A, is the receptacle, which is designed to receive the mixed paintand, B, is the agitator frame.

I), are loop shaped beaters extending downwardly from the cross bars ofthe frame into proximity with the bottom of the receptacle. The beaters,b, are preferably in the form of a square loop as shown moreparticularly in Fig. 3, and are set at an angle in the crossbars.

C, are double angle-irons secured to the sides of the frame and designedto secure the cross bars, 0, of the frame at certain distances apart.The upper end of the angle irons, O, are sup-- ported on the brackets,D, which are secured to the sides of the receptacle.

E, are brackets, which on one side are secured to the side of thereceptacle and at the other are adj ustably secured to that side. Theouter ends of the brackets, E, extend over the angle-irons, O.

F, is a center bar which extends from one end of the frame to the otherand is secured to the cross bars, and, G, is a T-shaped 'slotted bracketsecured on the end of the center bar.

H, is a spindle which has a crank, it, the crank pin, h, of whichextends into the slotted bracket, G. I

I, and, J, are bevel gears and, K, the pulley from which thevertical'standard is driven.

It will now be seen that upon the revolution of the vertical spindle, H,the frame, B, will derive a vibratory reciprocating motion at the bottomof the receptacle in which the mixed paint is placed and consequentlythere will be no possibility of the paint settling a the bottom.

My invention is more particularly designed for keeping the paintthoroughly mixed when it is designed to use itinthe dipping process, itbeing very important that thepaint throughout is of the same thickness.The frame is kept continuously vibrating during the period that thepaint is being used and even when the machine is stopped over night Ifind in practice that my agitating frame when set in motion will soonstir up all the particles and reduce the thickness of the paint to itsnormal density.

What I claim as my invention is- 1. In combination, with a paintreceptacle,

free fromv interior obstructions, a frame carrying downwardly extendingbeaters located in proximity to the bottom thereon supports for saidframe extending from the receptacle walls near the bottom whereby thereceptacle above the frame is free from obstruction,and means forreciprocating said beaters substantially as described.

a 2. An agitating frame supported parallel with the bottom of thereceptacle and in proximity thereto and having longitudinal double angleirons which are supported on brackets attached to the sidesof thereceptacle, the said frame being driven from the vertical spindle, H, bythe crank, h, the pin, h, of which extends into the slotted end of theT-shaped bracket at the bottom of the frame as and for the purposespecified.

3. The agitating frame, B, having a series of downwardly projectingbeaters, b, and the double angle irons, 0, connecting the cross bars ofthe frame together, in combination with the brackets D, and brackets, E,arranged as and for the purpose specified.

CHARLES JOHN MCLENNAN.
